C++ Thread使用类成员函数

C++ Thread使用类成员函数

#include <thread>
#include <iostream>

using std::cout;
using std::endl;
using std::thread;

class Job {
public:
  Job(int m) : _m(m){}
  void doSomeThing(int a, int b) {
    int c = a + b + _m;
    cout << "c : " << c << endl;
  }
private:
  int _m;
};

int main() {
  Job j(3);
  thread t(&Job::doSomeThing, &j, 1, 3);

  t.join();
  return 0;
}

 

创建线程thread t(&Job::doSomeThing, &j, 1, 3)时需要传入实例化对象Job j的引用。
